Hyperspermia
Hyperspermia
Condition in which a male has an abnormally large ejaculate volume
In medicine, hyperspermia is a condition in which a male has an abnormally large amount of semen or ejaculate volume[1] and is generally defined when the ejaculate is above 5.5 mL.[2] It is the opposite of hypospermia, which is defined as a semen volume of less than 1.5 mL.

| Aspermia—lack of semen; anejaculation |
| Asthenozoospermia—sperm motility below lower reference limit |
| Azoospermia—absence of sperm in the ejaculate |
| Hyperspermia—semen volume above upper reference limit |
| Hypospermia—semen volume below lower reference limit |
| Oligospermia—total sperm count below lower reference limit |
| Necrospermia—absence of living sperm in the ejaculate |
| Teratospermia—fraction of normally formed sperm below lower reference limit |
Hyperspermia alone does not appear to influence sperm health. However, large volumes of ejaculate may have lower relative volumes of sperm, leading to low fertility.[3][1]
In some cases, high semen volumes can be a symptom of male accessory gland infection.[4]
